## Beispiel { #example }

Hier ist ein Beispiel für eine *Pfadoperation* mit Parametern, die einige der oben genannten Typen verwenden.

{* ../../docs_src/extra_data_types/tutorial001_an_py310.py hl[1,3,12:16] *}

Beachten Sie, dass die Parameter innerhalb der Funktion ihren natürlichen Datentyp haben und Sie beispielsweise normale Datumsmanipulationen durchführen können, wie zum Beispiel:

接下来，使用 `__init__` 声明用于**参数化**依赖项的实例参数：

{* ../../docs_src/dependencies/tutorial011.py hl[7] *}

本例中，**FastAPI** 不使用 `__init__`，我们要直接在代码中使用。

## 创建实例

使用以下代码创建类实例：

{* ../../docs_src/dependencies/tutorial011.py hl[16] *}

这样就可以**参数化**依赖项，它包含 `checker.fixed_content` 的属性 - `"bar"`。

## 把实例作为依赖项

然后，不要再在 `Depends(checker)` 中使用 `Depends(FixedContentQueryChecker)`， 而是要使用 `checker`，因为依赖项是类实例 - `checker`，不是类。

## 例子

下面是一个*路径操作*的示例，其中的参数使用了上面的一些类型。

{* ../../docs_src/extra_data_types/tutorial001_an_py310.py hl[1,3,12:16] *}

注意，函数内的参数有原生的数据类型，你可以，例如，执行正常的日期操作，如:

   **2. Installing **TensorFlow** (TF) CPU prebuilt binaries**
   
   
   *TensorFlow release binaries version 1.6 and higher are prebuilt with AVX instruction sets.*
   
   
   Therefore on any CPU that does not have these instruction sets, either CPU or GPU version of TF will fail to load.
   

                  SetMultimap<String, Integer> filter(SetMultimap<String, Integer> multimap) {
                    multimap.put("foo", 17);
                    multimap.put("bar", 32);
                    multimap.put("foo", 16);
                    return filterKeys(multimap, not(Predicates.in(ImmutableSet.of("foo", "bar"))));
                  }
                })
            .named("Multimaps.filterKeys[SetMultimap, Predicate]")

## Exemplo { #example }

Aqui está um exemplo de *operação de rota* com parâmetros utilizando-se de alguns dos tipos acima.

{* ../../docs_src/extra_data_types/tutorial001_an_py310.py hl[1,3,12:16] *}

Note que os parâmetros dentro da função tem seu tipo de dados natural, e você pode, por exemplo, realizar manipulações normais de data, como:

  """Set CLANG_CUDA_COMPILER_PATH."""
  # Upon clang 19 drop the check for 16
  default_clang_path = '/usr/lib/llvm-18/bin/clang'
  if not os.path.exists(default_clang_path):
    default_clang_path = '/usr/lib/llvm-17/bin/clang'
    if not os.path.exists(default_clang_path):
      default_clang_path = '/usr/lib/llvm-16/bin/clang'
    if not os.path.exists(default_clang_path):
